Description

ACKNOWLEDGEMENT OF FEDERAL RESEARCH SUPPORT

This invention was made with government support under FLA-APO-04158 awarded by the Cooperative State Research, Education, and Extension Service, USDA. The government has certain rights in the invention.

Genus and species: Philodendron scandens oxycardium.

Variety denomination: ‘UFM1’.

BACKGROUND OF THE NEW PLANT

The invention relates to a new and distinct variety of Philodendron scandens oxycardium plant named ‘UFM1’. ‘UFM1’ originated by exposing cuttings of Philodendron scandens oxycardium, not patented, to gamma-ray radiation in Gainesville, Fla. After treatment, the cuttings were grown in a controlled environment in Apopka, Fla. The inventors selected the new Philodendron approximately 1 year later as a single branch mutation within the population of treated plants.

Asexual reproduction of the new cultivar by tip cuttings in a controlled environment in Apopka, Fla. has shown that the unique features of this new Philodendron are stable and reproduced true to type in successive generations of asexual reproduction.

Plant Breeder's Rights for this cultivar have not been applied for. ‘UFM1’ has not been made publicly available more than one year prior to the filing of this application.

SUMMARY OF THE INVENTION

The cultivar ‘UFM1’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘UFM1’. These characteristics in combination distinguish ‘UFM1’ as a new and distinct cultivar of Philodendron:

• • 1. Very small, narrow green leaves.
  • 2. Compact vines with short internodes and dense growth habit.
  • 3. Vines that produce lateral branches.

DESCRIPTION OF THE PHOTOGRAPHS

This new Philodendron plant is illustrated by the accompanying photographs which show the plant's overall appearance. These photographs show the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Philodendron.

FIG. 1 shows a side perspective view of a typical plant of ‘UFM1’ grown for 12 weeks in a 10 cm diameter container.

FIG. 2 shows a close-up view of typical vines and leaves of ‘UFM1’.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘UFM1’ with color terminology in accordance with The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary significance are used. The aforementioned photographs and following observations and measurements describe plants grown in containers in Apopka, Fla. during the spring and early summer in a glass-covered greenhouse. Plants were grown using practices and under conditions that approximate those generally used in commercial Philodendron production. During the production of the plants, day temperature ranged from about 29° C. to 35° C., night temperature ranged from a bout 18° C. to 26° C. and light levels were about 2,500 foot-candles. Plants were grown from single stem cuttings and were about 4 months old when the photographs and the detailed description were taken.

COMPARISON WITH PARENTAL AND KNOWN CULTIVARS

‘UFM1’ differs from plants of the parent, the species oxycardium, in the following characteristics:

• • 1. ‘UFM1’ has leaves that are much smaller and narrower than leaves of the parent plant.
  • 2. ‘UFM1’ has leaves that are completely different in shape compared to leaves of the parent plant.
  • 3. ‘UFM1’ has internodes that are much shorter compared to internodes of the parent plant.

Comparisons were made with the variety ‘Brasil’ (patented, U.S. Plant Pat. No. 12,956). In side-by-side comparisons conducted in Apopka, Fla., plants of ‘UFM1’ differed from plants of the cultivar ‘Brasil’ in the following characteristics:

• • 1. ‘UFM1’ has leaves that are much smaller and narrower compared to plants of the cultivar ‘Brasil’.
  • 2. ‘UFM1’ has leaves that are completely different in shape compared to leaves of the cultivar ‘Brasil’.
  • 3. ‘UFM1’ has leaves that are green compared to the cultivar ‘Brasil’ that has green and yellow green variegated leaves.
